Chronic inflammation is a significant risk factor for iron deficiency, with up to 40% of hospitalized patients with chronic disease suffering from anemia of inflammation. The intricate link between the body's immune response and iron metabolism is controlled by a master regulator hormone called hepcidin, which explains why inflammation decreases iron absorption. Understanding this process is key to managing health conditions like inflammatory bowel disease, rheumatoid arthritis, and chronic infections.

According to the World Health Organization, iron deficiency is the most common micronutrient deficiency globally, affecting nearly 30% of the world's population. While often considered separately, a complex biological relationship exists, and many studies are exploring: what does vitamin D have to do with iron?.

Worldwide, iron deficiency is the most common nutritional deficiency, and at the core of its pathology is a powerful regulator: the hormone hepcidin. While low iron intake is a primary cause, surprisingly, high levels of this specific hormone can also cause iron deficiency by blocking the body's ability to utilize stored and dietary iron.

Inflammation is a key driver of increased hepcidin levels, which can lead to functional iron deficiency and anemia in chronic diseases. Managing hepcidin is crucial for improving iron availability, with certain supplements showing promise in research.

As part of a host defense mechanism known as nutritional immunity, the body actively withholds iron from invaders. This critical tactic explains why we can't give iron during infection, as doing so provides essential nutrients to pathogens, potentially exacerbating the illness and interfering with antibiotic efficacy.

Anemia of inflammation (AI), or anemia of chronic disease (ACD), is the second most common cause of anemia worldwide, affecting people with conditions like autoimmune disorders, cancer, and chronic kidney disease. This guide will detail how to treat anemia due to inflammation by addressing the root cause, identifying key symptoms, and exploring medical treatment options.

According to research, infections, especially chronic ones, are frequently associated with a form of anemia. The surprising reality behind this phenomenon is that yes, a bacterial infection can cause low iron by disrupting the body's iron regulation as a defensive strategy.
